Intel is releasing an enhanced RealSense camera model in the week of December 3 2018 called the D435i. It is identical to the D435 in most respects but adds an integrated Inertial Measurement Unit (IMU). The standard D435 model continues to be available alongside the D435i.
"Intel RealSense Depth Camera D435i combines the depth sensing capabilities of the D435 with the addition of an inertial measurement unit (IMU). For great scans, an IMU provides an extra set of data allowing for better dense reconstruction. Alternately, in robotics, the Robotic Operating System (ROS) takes this input for your robot so your can understand its position in the world".
D435i includes a BMI055 inertial measurement unit, and IMU data that is time stamped to align with depth data as needed. Initial support for D435i is already included in the RealSense SDK 2.0 software (though the firmware part of the support is not available publicly yet). The camera can be pre-ordered now on Intel's online Click store.
Intel have also released additional information about the D435'si IMU functions on the page below:
Update 1: here is the official Intel Newsroom announcement of the D435i:
Update 2: Dorodnic the RealSense SDK Manager has added more information about the D435i in regard to the RealSense SDK 2.0.
